Changing the Parts in the Active Model

The active model is the parts or regions that are available for repair during the surface repair session.

You select the active model in the Surface Repair Options dialog after launching the Surface Repair tool. This feature allows you to simplify a complex geometry by working with smaller groups of parts or regions for diagnostics and repair. You can change the active model at any time in the Surface Repair tool.

To change the parts or regions in the active model:

  1. Click Reset Parts... or Reset Regions... at the bottom of the Surface Repair tool.
    The Surface Repair Options dialog, which has similar options to the dialog that appears when you launch the Surface Preparation tool, appears. The only exception is the Faces to show on startup menu, which allows you to display All Faces or No Faces only. The Currently Visible Faces option is not available, as changing the parts means that the currently visible faces are unlikely to be in the new active model. The default Geometry Description is set to the description that is currently being repaired.

  2. Click the Select button. In the Select Objects dialog, select or deselect a part or region, click the button to the left of that item as shown:
  3. In the Select Objects dialog, select or deselect a part or region and click OK.


Changing the parts in the active model makes the following changes to the surface repair session:
  • All face, edge and/or vertex selections are deselected.
  • The surface diagnostics and feature diagnostic results are deselected and the Diagnostics panel returns to its default state. However, the state of the diagnostic checkboxes is maintained.
  • The Edit Connected Surfaces diagnostics are deselected.
  • All user-defined sets are deleted and entities in the default set are deselected.
  • The Undo/Redo stacks are deselected.
  • The single and multi-parts Merge/Imprint pairs lists are deselected.
  • Faces selected for the Intersect/Boolean Faces Tool are deselected.
  • Faces selected for Find Leak Path are deselected.
  • The list of part surfaces and part curves available in the Part Surface/Part Curve Edit group box is automatically updated to match the new parts in the active model. The same is true for regions, regarding boundaries and part curves.

When projecting vertices, the Project Vertices tool temporarily replaces the Surface Repair tool. Therefore, you are unable to change the parts in the active model while projecting vertices, as the Reset Parts... button is unavailable.
